We have been installing solar energy systems since 1997 but have been facing with one peculiar challenge.

In an electric inverter/UPS, whenever electricity goes off, inverters/UPS comes ON handy. However in solar inverter/UPS, we have to use manual ON/OFF so as one can use the solar inverter/UPS for a said duration even when there is no power cut. However this is felt as an inconvenience by some of the users.

Is there any solution of auto-change-over with out loosing the benefit of using solar inverter/UPS even when there is no power-cut.
